Product Overview

A 30mm silicone suction cup provides a compact contact footprint for a custom suction attachment. Its size is useful when the available surface is limited, but the entire rim still needs a suitable seating area. The surface condition and the way the cup is loaded determine whether that contact can be maintained.

Place the cup on a clean, smooth, nonporous area that extends beyond the full rim. A small cup positioned partly over an edge or surface joint cannot form the same continuous contact as one seated on an uninterrupted area. The attachment feature connected to the cup should also allow the intended load to act without unnecessarily peeling a side away.

Assess the cup in its actual arrangement, including the orientation of the surface and any movement of the attached item. The 30mm designation identifies size rather than a guaranteed holding load. If the cup is repeatedly removed, keep its contact face free of cuts and residue before refitting it. Release the edge deliberately during removal instead of sharply pulling the attached component, which can distort the cup or stress its connection.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. Assess rim compliance with the attachment loaded in its intended direction, including any movement that could peel one side away.
Custom geometry: Its size is useful when the available surface is limited, but the entire rim still needs a suitable seating area.
Fit evaluation: A small cup positioned partly over an edge or surface joint cannot form the same continuous contact as one seated on an uninterrupted area.
Color & OEM: Custom colors; OEM markings outside the suction contact face.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
